It's been many years since I read a few of Gerald Edelman's books, so my memory of their content has faded. Anyway, he made a similar distinction between primary consciousness and higher consciousness. An Amazon search on his name will give a longer list of the books he wrote.
For anyone interested in these issues, I'd encourage getting in hand Damasio's layout of core/extended consciousness and core/extended self in The Feeling of What Happens.
For introduction it is easy to view Antonio Damasio on his book Self Comes to Mind, especially 4, 5, 7.
